USGS reports: "On Kīlauea Volcano's East Rift Zone, the perched lava pond in Pu‘u ‘Ō‘ō's west pit remains active. Additional overflows of the pond levees have been slowly filling the bottom of the west pit and raising the floor."

April 23, 2018: Lava from Kilauea's summit lava lake overflows intermittently out of its Overlook crater onto the floor of Halemaumau Crater

In this April 23, 2018 photo provided by the U.S. Geological Survey, a helicopter view of Kilauea Volcano's Halemaumau crater shows the extent of the largest overflow (silver gray) of the lava lake in Hawaii Volcanoes National Park on Hawaii's Big Island. Lava from Kilauea's summit lava lake continues to overflow intermittently out of its Overlook crater onto the floor of Halemaumau Crater, after recording its largest overflow since the summit vent opened up 10 years ago. less

USGS reports: "The collapse of the Pu‘u ‘Ō‘ō crater floor yesterday (April 30) produced a large amount of red ash that was deposited around Pu‘u ‘Ō‘ō, as well as blown farther downwind, with a thin dusting of ash reaching uprift as far as Mauna Ulu. This photo, taken between 1-2 km (0.6-1.2 miles) from the 61g vent, shows a layer of red ash on top of active 61g lava flow surface breakouts."

USGS reports, "Puna residents reported to HVO geologists the recent appearance of ground cracks on a couple of roads in and around Leilani Estates. No steaming or heat were observed to originate from the cracks, and the cracks are currently still small (no more than several inches across). These cracks result from deformation of the ground surface due to the underlying intrusion of magma. Earthquake activity remains elevated in this area due to the ongoing intrusion."

May 3, 2018: Magnitude-5.0 earthquake strikes the Big Island

The temblor Thursday is the latest and largest in a series of hundreds of small earthquakes to shake the island's active volcano since the Puu Oo vent crater floor collapsed and caused magma to rush into new underground chambers on Monday. Scientists say a new eruption in the region is possible.

Hawaii's Kilauea volcano erupted Thursday, sending lava shooting into the air in a residential neighborhood and prompting mandatory evacuation orders for nearby homes. Hawaii County said steam and lava poured out of a crack in Leilani Estates, which is near the town of Pahoa on the Big Island. (U.S. Geolgogical Survey via AP)
